SEPTIC TANK.

,application filed ecemher 2, 1908.

'o whom it 'may conecta:

it known that l, rltver's'r TW. Heirs- ;icik, a citizen of the United States, and a resident ot Staunton, in the county of iiaconpin and lState ot illinois, have invented a new and improved ySeptic Tank, ot which the following is a fnll, clear, and exact. description.

T his invention relates to septic tanks tor sewage disposal and purification, and relates inore particularly a septic tank having an inlet cl ainher and an ontlet chaniloer opening into the tank, Walls separating the chainhers troni the tank, a dividing Wall eX- tending longitudinally ot the tank into the inlet chainher, inlets discharging Within the inlet chainher, battles arranged transversely ot the dividing Wall, an overflow Within the inlet chamber in case the outlets are clogged si that the inaterial in the tank backs up, escape openings leading troni the tank to the outlet charnher, valves controlling the opcnings, an overnow Within the outlet chainher, drain valves for einpt fing the tank, and an outlet Within the otfet chainher, the oiferllon, the drains and the outlet discharging into a connnon drain Jipe.

rihe object or the invention is to provide a siniple, conipact and efficient septic tank tor sewage disposal, in vwhich the sewage is partly purified by ineans of fermentation or pntrefaction, in which the passage or' the sewage therethrough can he readily controlled, which perinits the sewage to escape in case the outlets clogged so that the inaterial hacks up Within the tank, and Wl' ich is provided with -inanholes, and inanhole covers of special torni so that the tank can he tightly closed, While access can be easily had thereto when necessary.

The invention consists in the construction and cinnlaination or parts to he inore .tally described hereinafter and particularly set 'orth in the claiins.

Reference is to he had to trie accompanying drawing: forming a part of this specilication, in which siinilar characters or retcrence indicate corresponding parts in all the Views, and in Which- Figure l is a horizontal section of an einhodiinent of niy intention; F 2 is a longitudinal section on the line 2 2 ot Fig. l; is transverse section on the line 53m-3 ot lli 1 l; Fig. el is a similar section on Y i" 5 is a similar the line delle or lig. l, rig

Before proceeding to a inore detailed eX- planation or niy invention, it should he clearly understood that the tank can he used with any suitable systein ot senfage disposal in which such devices are employed. ln certain systeins ot sewage disposal the sewage is allowed to pass into septic tanks Wl ere it is partly pnrilied hy what is known as the "septic process, in which advantage is taken ot the tact that sewage is a highly pntrcscihle fluid, richly charged with pntretive bacteria, in order to decompose it hy its own ordinary processes of bacterial tei` mentation or putrefaction. ln this Way it is brought into a condition which perinits it to he readily nitritied `when it is snhseq ently brought in contact with the earth. Furtherinore, When in this condition the suspended niatters con'nnonly known as sludge can pass partly or wholly into solution. ln the septic process the sewage is allowed to stagnate, ferment and nntreiy in the sept-ic tanks L for a period of onsideralole length. Alfter escaping troni the septic tank the seW- age can he filtered or otherwise operated upon in accordance With the systein ot its disoosal.

l prefer to fashion the septic tank of iny invention troni concrete, though any other siinilar inaterial adapted for the purpose, for eiainple, hricknork or masonry can also be employed. This detail oi constrinftion as .tell as others of the details, can loe Varied in accordance With special conditions and individnal preference Without departing troni the underlying soirit of the invention.

Referring more particularly to the dranY` ings, l provide a inain chaniher or tank l() which is substantially rectangular in forni and preferably has the corners ll rounded. l eedless to say, the toi-1n ot the tank is nniniportanr, and can he altered as necessary or desired. rit one end the tank has an inlet hainher l which i ractically toi-ins an eX- tension ot the tank being separated therextroni hy a Wall 2G. .fr Wall ll extends longitndinally ot the tank and divides it into tivo compartments l-l and likewise divides the inlet chainher into tivo compartments l, eX- tcnding into the inlet chamber to the rear wall thereof. in inlet or supply pipe l@ extends into the inlet chainher and has a cross pipe 17 within the same. The cross pipe has inlets 18, each of which empties into one of the compartments 15. Valves 19 control the inlets 18.

At the rear wall, the inlet chamber has a shelf 20 forming a trough 21 under the cross pipe. The latter has a discharge nozzle 22 controlled by a valve 23 and adapted to dis` charge into the trough. A drain pipe 24 is arranged at the outside of the tank and has an open end 25 arranged in an opening of the side of the inlet chamber to receive material flowing into the trough. By means of the trough 21 and the discharge nozzle 22 the material can be diverted into the drain pipe 24 when it is desired to clean or repair the tank. The trough also constitutes an over` flow, in case the outlets are clogged so that the material in the tank backs up, and determines the upper limit of the sewage within the tank. The partition wall 26 divides the inlet chamber from the tank and extends to the roof of the tank. It has openings 27 therethrough so that it does not interfere with the movement of the sewage through the tank.

At the end remote from the inlet chamber, the tank has an outlet chamber 28 separated from the tank by a dividing wall 29. The latter has escape openings 30 therethrough at which are arranged controlling valves 33 having screw stems 34 arranged in supporting brackets 35 mounted upon the valve casings. At the upper ends, the valve stems have hand wheels 36 by means of which they can be conveniently manipulated. The compartments 14 of the tank have baffles 37 arranged transversely thereof and forming arches whereby they are spaced from the bottoms of the compartments and do not interfere with the flow of the sewage through the tank except in so far as it is essential in the system of purification; that is to say, the battles retard the flow sufficiently to allow the purifying action to run its course.

Vithin the outlet chamber is a transverse weir or overflow wall 38, having about halfway from the bottom a shelf or stop 39, preferably troughed. The sewage passes over the wall 38 to the bottom of the chamber where it can escape through an outlet 40 connected by a pipe 41 with the drain pipe 24.

Within each of the compartments 14, at the bottom thereof, is a drain 42 discharging into a pipe 43 communicating with the drain pipe 24. Each drain has a preferably tapered sleeve 44 extending through an opening in the bottom 45 of the tank and communicating interiorly with an enlarged section 46 of the pipe 43. Above each sleeve 44 is a bracket 47 supported upon uprights 48 extending through the bottom of the tank and mounted upon one of the sections 46. A tapered valve plug 4D is adapted to seat in each of the sleeves 44 and is rigid with a valve stem 50. The latter have threaded engagement with the brackets 47, and further each has at the upper end a handwheel 51 by means of which it can be conveniently manipulated.

The top or roof 52 of the tank preferably slopes in opposite directions from the dividing wall 13. It has a number of manhole openings 53 so that the interior of the tank is accessible for purposes of cleaning it, repair, and the like. Each manhole opening has a substantially rectangular frame 54 provided with an upwardly extending rim and having at one end an overhanging enlargement or iiange 56. A. cover 57 is mounted upon each frame and has a downwardly extending flange 58 adapted to engage at the rim so that the cover can seat evenly upon the frame. The latter at opposite sides adjacent to the overhang 56 has inwardly-projecting studs 59 adapted to be engaged by extensions (5() of the cover. Each of these extensions has a finger 61. Each cover can be swung upwardly, pivoting upon thestuds 59 until the lingers 61 engage at the under sides of the studs to hold the cover in an open position, resting against the overhang, as is shown most clearly in Fig. 6. Each frame has a staple or inverted U-meniber 62 adapted to project through an edge recess 63 of the cover to permit a lock of any suitable form to be applied to hold the cever in place.
